u.s. to dio trans conversion

I have posted in the past how easy it is to convert your stock elite-s trans to a true japan dio, don't know why the michigan boyz didn't jump on this as the only restriction the japan dio had was the cdi because the u.s. engine block was milled smaller, got my parts from vy cycles a long time ago, post if you are interested, dio trick of the trade= shhheee don't tell nobody

does this have anything to do with the OKO OEM Dio style clutch assembly? they have the JDM rear pulley as well?

from what i understand you can set up a "zx" trans thats the same as the real japanese dio. but overall the American one is better because its easier to find parts and tune.

What is a "ZX" trans?

And i'm fine with keeping my engine, trans castings, All I want is the rear pulley. More acceleration please!

you know your clutch is also a pulley system? it opens and closes just like the front pulley.

The ZX trans is fancy talk for front clutch and rear pulley. However its harder to tune and harder to find parts. you better off keeping the system you have now and just upgrading the pulley.

WOAH, wait, DIO trans had the clutch in the front and the variator in the rear?

Yeah I don't need that per say, but I do want the bigger pulley.

im not 100% on that, but i know its really weird.

if you just want a bigger pulley you can get that no problem. VTcycles has good ones for a very reasonable price.

wait, they have aftermarket rear pulleys at vtcycles? The pulley that is connected to the clutch?

I thought all they had were front pulley variators?

what the hah this is misleading

all "zx trans" is a larger REAR pulley/dio style

if you want acceleration tune for it! stock rear pulley is plenty for this, run stiff springs light rollers and big bore, nets you all the accel you'd want garanz

No, I want all the accel possible. This means jap dio rear pulley and different belt and an upgraded torque drive.

If they didn't put them on hopped up race scooters, I wouldn't buy one, but I don't care about going over 50mph. I want to zip to 50mph as fast as possible.

Hey, that's what i want too, but a top speed of 55!!

But i'm not spending a ton of $ to do it so i'm just doing the basics.
